Question

A digital circuit uses three inputs A, B and C connected to a combination of XOR gates as follows:
The output expression is given by:
Y = (A ⊕ B) ⊕ (B ⊕ C)
Which of the following Boolean expressions correctly represents the simplified output (Y) in terms of A, B and C?

Accepted Answer

Y = A ⊕ C

Answer

Y = A ⊕ C ⊕ B

Answer

Y = A'B + AB' + BC' + B'C

Answer

Y = A + B + C
